Anyone else notice how the rider has those jerry-cans finely balanced on his boot (thread 11).
All that and enjoying a Hamlet moment...... ( looks like a cigar between his fingers)

No, but someone once told me, a long time ago, that a jerry can with 4 gallons of petrol in it will float on water. I've never actually put the theory to the test; has anyone else? Theoretically it should work with 4 gallons of petrol in it but possibly not the cans maximum capacity of around 4 1/2 gallons???

whatever fluid there was in the can would be academic because it'd be the weight of the liquid, temperature, SG of the saline or fresh water and volume of air that would dictate the degree of buoyancy. But if it was full, it'd go straight down! There is probably a basic mathematical or physics formula out there somewhere. And guess what...., someone on the forum will have it handy!

The story goes that on D Day and following some of the Jerry cans of petrol was deliberately chucked over the side of the supply ships at anchor and allowed to make there own way to dry land. How much truth there is in this story I've no idea???

Well, gasoline does have a specific density that is less than water, (~0.75kg/l vs ~1.0kg/l) so it will float on it's own, the old "oil floats on water". If enclosed in a Jerry Can I imagine it would resist sinking, but not float as though the Jerry can were empty of fuel and filled entirely air (~0.001kg/L).
Some amount of air in the can would improve buoyancy to offset the fuel.
That is as far as my memories of high school sciences take me on this topic, and I could have missed something. Only reason I recall this much is from troubleshooting water in fuel issues with a vehicle. Given a bottom sump in a fuel tank, water will be displaced into the pickup and be a right miserable bastard until the water is drained off, consumed by the engine, or bonded with methyl hydrate and more effectively consumed by the engine.

In Canadian Army speak they are still called Jerry Cans, despite being made of plastic and only rough facsimiles of their WW2 cousins, and the spout is still called a "horsec**k" because it's thick, flexible, and the length of a man's forearm, which is about the same as a...

Item in question:
Old and best version:
New and less reliable version:
We never denoted them by a Mark or Series number, there was not a HC Mk1 or HC Mk1* etc.
